Embodiment Construction

[0039] In order to make those skilled in the art better understand the present invention, a specific embodiment is used to further describe the present invention in detail below. Take, for example, a MID multimedia device equipped with a digital pen, camera, and microphone.

[0040] Created a concept map of a one-day meeting program on MID with a digital pen (eg Figure 5 (a) shown). MID parses the above-created concept map structure through the parsing device, and uses four stages of preprocessing, dividing the map into sub-graphs, extracting stroke blocks, and generating the concept map structure to obtain the concept map structure created by the user (such as Figure 5 (b) shown). After that, the nodes of the hand-drawn concept map are identified by the handwriting recognition engine, and the meanings of the nodes of the hand-drawn concept map are obtained (such as Figure 5 (c)), and obtain the relationship between nodes, links and node links in the concept map. In thi...

Abstract

The invention relates to a method for generating a multi-media concept map, which belongs to the man-machine interaction field. A concept map is created by using a digital pen, a multi-media object is input through multiple channels, the input multi-media information is organized in a form of the concept map to generate a multi-media concept map including various multimedia information, and meanwhile, and the multi-media concept map is edited by adopting an interactive mode of pen gesture to support quick look of the multimedia information. The invention supports the digital pen to draw the concept map, simulates the traditional notes taking method, conforms to the habits of users and is more natural and more effective; and the invention supports to automatically establish the correlation between the node of the hand-drawing concept map and the multimedia object, transforms the concept map created through the digital pen into a multi-media concept map and further improves the efficiency of generating the multi-media concept map.

Description

technical field [0001] The invention belongs to the field of human-computer interaction, and in particular relates to a method for generating a multimedia concept map supporting multi-channel input. Background technique [0002] A concept map is a graphical representation of a topic's concepts and their relationships, and is a tool used to organize and represent knowledge (References: Novak, J.D. and A.J. The Theory Underlying Concept Maps and How to Construct Them, Technical Report IHMC CmapTools 2006-01, Florida Institute for Human and Machine Cognition, 2006.). It includes concepts and relationships between concepts, using nodes to represent concepts and lines to represent relationships between concepts. The concept map is composed of a series of hand-drawn strokes with time sequence information, each stroke is composed of a set of point sequences containing two-dimensional coordinate information. The concept map expresses and thinks in an intuitive and vivid way, which...
